IntelliJ IDEA 2019.2 Help

XPath and XSLT Support

  • XSLT support is available in all XML files that declare the XSLT-Namespace http://www.w3.org/1999/XSL/Transform on their root element.

  • IntelliJ IDEA supports XSLT versions 1.0 and 2.0, XPath versions 1.0 and 2.0.

  • An XSLT 2.0-capable processor (for example Saxon 9-HE) should be added to the classpath of a module that is used to run a Style Sheet, and placed in front of JDK. See Module dependencies.

IntelliJ IDEA lets you evaluate expressions against the currently focused document, including support for the document() function to make cross-document queries. You can also evaluate an expression against multiple XML documents in the Find in Path style using the Find by XPath action.

You can configure to highlight matching expressions in the current editor or to show a list of matching lines in the Find window. Editing XPath expressions is enhanced by on-the-fly error-checking including a set of customizable XPath Inspections and a wide range of code completion suggestions.

IntelliJ IDEA also lets you display a unique XPath expression for a selected element in the editor by choosing View | Unique XPath from main menu.

XSLT support is not limited to XPath expressions, it also supports a wide range of XSLT constructs, like checking the existence of templates that are called via xsl:call-template and their parameters, refactoring and navigation enhancements. The bundled XSLT debugger plugin allows you to debug XSLT stylesheets.
